dc.description.abstract
Fatty acids are involved in the regulation of many physiological pathways, including those involved in gene expression and energy metabolism. Through effects on these pathways, fatty acids may have lifelong impacts on offspring development and metabolism via maternal supplementation. Therefore, our objective was to investigate the impact of supplementing a source of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) during late gestation on productive and metabolic responses of ewes and their offspring. Eighty-four gestating ewes (28 pens) were blocked and randomly assigned to a diet with 0.39% added fat during the last 50 d of gestation (d −0). The fat sources were Ca salts of a palmitic fatty acid distillate (PFAD) or EPA + DHA. After lambing (d 1), all ewes and lambs were placed on the same pasture. The ewes were weighed and BCS was measured on d −50, −20, 30, and 60 (weaning) of the experiment. Blood samples were taken from the ewes on d −50, −20, 1 (lambing), 30, and 60. Milk yield and composition were measured at 30 d postpartum. Lambs were weighed and bled at d 1, 30, and 60, and ADG was calculated. All plasma samples were analyzed for glucose and NEFA. Ghrelin, prostaglandin E metabolites (PGEM), and the prostaglandin D2 metabolite 11β-PGF2α were measured in d −20 ewe samples. Insulin and adropin were measured in lamb samples at d 60. There was no difference on ewe BW (P = 0.48) or BCS (P = 0.55), or plasma concentrations of glucose (P = 0.57), NEFA (P = 0.44), ghrelin (P = 0.36), PGEM (P = 0.32), and 11β-PGF2α (P = 0.86) between ewes supplemented with PFAD or EPA + DHA. Neither milk yield nor its composition was different (P > 0.10) among treatments. Lambs born from ewes supplemented with PFAD or EPA + DHA did not have different BW (P = 0.22), ADG (P = 0.21) or plasma NEFA (P = 0.52), glucose (P = 0.50), insulin (P = 0.59), and adropin (P = 0.72) concentrations. These results suggest that supplementation of EPA and DHA during late gestation did not affect ewe metabolic profile or milk production. Lamb performance and metabolism through weaning were not affected by maternal supplementation with an enriched source of EPA and DHA.
